Need some help. Cheater or not?

I was trying this track(waterfront lvl44) for already 3 days but the best time I got was 4:06. He has a lot of mistakes in his run and he still gets that great time 4:04. And his stats talk by itself about him.http://nfs-s.com/nfsw/GAGITO
Im not expert so want to hear some answer who know how to detect cheaters.

Re: Need some help. Cheater or not?

I know that his stats are banned but he swears that he didn't use any cheat in that run, I really doubt about that, anybody can try to make run on that track to see what's the best time possible without powerups?
And any tips about his run whether his cheating or not! Because I want to prove him that he is cheater...
